Product Overview

As an industry-leading expert in precision CNC machining, we specialize in resolving the manufacturing challenges associated with large-scale, high-tolerance, and thin-walled disc-shaped components. This precision indexing baseplate is custom-engineered for applications in semiconductor manufacturing, precision robotics, and high-end automation systems, delivering exceptional structural stability and repeatable positioning accuracy even within extreme industrial environments.

Leveraging over 20 years of precision machining expertise, we employ proprietary stress-relief techniques to ensure that our large-diameter baseplates maintain micron-level flatness—even after undergoing complex cutting operations.

Core Technical Advantages

Micron-Level Geometric Tolerance Control
We utilize advanced 4-axis and 5-axis CNC machining centers to complete the machining of all complex hole patterns, cavities, and dowel pin bores in a single setup. This fundamentally eliminates cumulative errors, ensuring that positional tolerances are maintained within ±0.01mm and that flatness meets the most rigorous assembly requirements.

Superior Material Stress Management
For large-diameter components made from aluminum alloys or stainless steel, we employ specific heat treatment and vibration aging processes to prevent deformation caused by internal stress release during long-term operation—a critical requirement for applications within semiconductor vacuum environments.

Semiconductor-Grade Surface Finishing
We provide surface finishing solutions that meet strict cleanroom standards—including hard anodizing, electroless nickel plating, and electropolishing—to ensure the baseplates exhibit exceptional corrosion resistance, low outgassing rates, and superior surface hardness.

100% Digital Quality Assurance
Prior to delivery, every baseplate undergoes a comprehensive inspection using Coordinate Measuring Machines (CMM), optical projectors, and laser surface roughness testers. A unique serial number engraved on the edge of each component ensures precise traceability of production batches and inspection data.
